Mint.  Yummy but soooo invasive.  Once you plant mint you have mint forever.  Take it out and looky there - it's back.  But since mojitos have a magic spell on me at the moment, I might just put some in the side yard.  It's fabulous to walk through a big patch of it.
Soapy water will supposedly take care of aphids but you have to then strip them off and wash away the soap.
Gardening - I remember those days.  I really enjoyed doing that....  and you say if I garden I don't have to clean house?
